Answer:
x = 1.02.
Step-by-step explanation:
The x is a factor worked out from the annual interest written as a decimal fraction.
So we have 2% = 2/100 = 0.02.
The amount at the end of the first year is $100 + 0.02*100
= $100* 1.02, and in the second year it will be $100* 1.02^t where t = 2 and so on.
So we see that x in the given expression is 1.02.
Answer: Yes. On average, it takes about 455 days for 1 person to throw away 1 ton of garbage, so just over 1 year.
Step-by-step explanation: The average person throws away 4.4 pounds of trash daily. So, the way to figure this out is 2,000 divided by 4.4 to find out the number of days it would take to throw away 2,000 pounds of trash.
Answer:
a = -7
B= *4
Step-by-step explanation:
Answer:LetAbe the event that the person is taking the drug. We are told thatP(A) = 0.05.LetBbe the event that the person has migraines. We are told thatP(B) = 0.1.Further, we are told thatP(B|A) = 0.3. Using the rules for conditional probability,P(A|B) =P(A∩B)P(B)=P(B|A)P(A)P(B)=0.3·0.050.1=0.15.The probability that a migraine sufferer takes the drug is 15%.
